Doerr Lab

We study how bacteria build and maintain a healthy cell envelope and resist killing by antibiotics.

Thrilled to share the first paper of my PhD @DoerrLab is live at PLOS Pathogens! https://t.co/MJ1F88SX96

Baskin Lab researchers have uncovered the surprising role played by a “three-tailed” fat molecule in cellular survival during heart attack and stroke: protecting the cells against damage when oxygen runs out. https://t.co/pLiotkshe0

Research led by @weillinstitute postdoctoral fellow Megan Keller in @DoerrLab reveals how sugar-phosphate buildup disrupts cell wall synthesis, offering clues to fight drug resistance. https://t.co/6OFTOE8fve

Congratulations to Dr. Manuela Alvarado Obando for an amazing PhD defense seminar! Felicidades, and on to more greatness! @CornellMicrobio @ManuelaAlv95 https://t.co/c9oi3ugwkQ If you are looking for an exceptional postdoc (and are in the greater NYC area), reach out to her!

[Heather Feaga @FeagaHeather]

Latest preprint from our lab led by grad student @cassidyprints and her undergrad mentee @IsabellaNLin. She examines conservation and features of the programmed ribosomal frameshift in prfB. Presented by Cassidy at #GRC stress!

What a phenomenal seminar today at @CornellPathogen by @Hatzios_Lab — a tour de force of using chemical proteomics to discover new mechanisms of redox signaling in gut infection!🤩🤩🤩

Out now in @NatureComms:

Control of bacterial cell wall autolysins by peptidoglycan crosslinking mode

Our new paper out in @PLOSPathogens today: https://t.co/K68SlqMCjc We find that resistance/tolerance to antimicrobial peptides is slightly more complex and dynamic than your "average" antibiotic resistance. Nice work by @AndyMurtha et al.!

[Phutung Research Institute @phutungri]

We demonstrated a lowcost device that can detect deadly bacteria in drinking water. It shows, once again, that worldclass research can flourish in Nepal, despite limited resources. Here is news release by
@OpticaWorldwide
highlighting the important result. https://t.co/1red1v7BR2

[Ethan Garner @fleshball]

Announcing the 2025 Bacterial and Archaeal Cell Biology and Development @GordonConf. We have amazing speakers and discussion leaders confirmed and look forward to (again) having our minds blown by all the remarkable science. Applications will start being accepted in the fall.

And that concludes our workshop in Nepal! Successfully cloned NDM carbapenemases? Check! Isolated bacteria that can eat styrofoam and motor oil from Bagmati River AND fluoresce under UV? Check! @rajbhandari_33 @karmamonima @guavadk @utsavRIBB @AnkitSh03786959

[Doerr Lab @DoerrLab]

Excited to kick off a bacterial genetics workshop at RIBB Kathmandu! We will be cloning some clinical NDM enzymes. ⁦@rajbhandari_33⁩ ⁦@karmamonima⁩ ⁦@guavadk⁩ ⁦@utsavRIBB⁩ @ankitsh03786959 ⁦@drakarki⁩

@IanH77 My undergrad biology classes have criminally misled me! Turns out there there is both Arrottle's Lantern, and Aristotles' Lanten!

[Doerr Lab @DoerrLab]

I asked AI to draw an image of the bacterial OM. This is what it came up with. My lab better pivot to the new hot field of outer pemmoccan homeostasis! And how is that one otter equally distributed among daughter cells? Lots of cool open questions!

[Doerr Lab @DoerrLab]

Huge Congratulations to Dr. Megan Renée Keller @MRKmicrobes for successfully and epically defending her PhD today! #proudPI @Cornell_BBS

[Heather Feaga @FeagaHeather]

What an honor for @cassidyprints and @CornellMicrobio to host Dr. @Nancy_Craig777 for our distinguished Portraits of a Microbiologist series. Thanks for returning to Wing Hall for such a moving and inspiring visit!
